In 1949 James R. "Jim" McQueen and Harper Hull purchased the Cottrell-Spoore Boatworks of Troy, New York. The company was named "The Trojan Boat Company" and moved the business to York, Pennsylvania. Soon they moved to Lancaster, Pennsylvania. Growth in sales after the Korean War necessitated additional facilities at Elkton, Maryland, and Niagara-on-the-Lake, Ontario, Canada. Trojan by 1968 had become the one of the largest producer of inboard motor boats in the world, employing over 700 people, most on their 26-acre site in a 142,000 square foot factory and adjacent truck depot at 167 Greenfield Road, Lancaster, Pennsylvania. In 1966 Trojan acquired the Shepherd Boat Company, Canada, manufacturer of up to 50-foot wooden motor yachts. The Elkton Plant, located on 26 acres of land at the top of the Elk River, opened in the spring of 1965. In the 30,000 square-foot industrial structure, the 42-foot leisure boat, as well as smaller craft, were built. The company launched its first pleasure craft into the Elk River on July 30, 1965. Originally all of the boats were built of wood. Transition to fiberglass hulls forced the company to become affiliated with Whittaker Marine Group, listed on the NYSE, which ultimately included Bertram Yacht, Trojan Yachts, Riva, Desco Marine, Kettenburg, Balboa Marine, and Coronado Yachts. Total sales of the Whittaker Marine Group reached between $250 and $350 Million in the early 70's. The Trojan Yacht Company of Lancaster, Pennsylvania ended production in 1992. The Elkton, which was also hampered by silting in the river, closed at the end of 1989. Carver Yachts under Genmar Holdings, purchased the Trojan Boat brand name and assets.
